I have a user with strange settings. If i try to find this user in /etc/group, i don't find it mentioned anywhere. But when I run the command "id username", it shows the groups the user belongs to.
uid=504(nicole) gid=501(admin) groups=501(admin) context=user_u:system_r:unconfined_t
[root@unix etc]# grep nicole /etc/group
The last command doesn't output anything.
Why is it happening such ? I am confused...
By the way, is it something like the user has been deleted from /etc/group, but the group database has not been updated. If so, where do I find the group database file ??
